Hi,
I finally got around to fixing various problems with apt-rpm when
used with
rpm5 -- the last being "apt-get update" hanging because of a bug in
rpm4compat.h.
Now it gets the lists and starts resolving dependencies, but it
complains
about the rpm internal dependencies for loads of installed packages:
The following packages have unmet dependencies:
ImageMagick: Depends: VersionedDependencies (<= 3.0.3-1) but it
is not
installable
Depends: PayloadFilesHavePrefix (<= 4.0-1) but it is
not
installable
Depends: CompressedFileNames (<= 3.0.4-1) but it is not
installable
Depends: PayloadIsBzip2 (<= 3.0.5-1) but it is not
installable
apr: Depends: PayloadIsLzma (<= 4.4.6-1) but it is not installable
[...]
I nuked these ancient tracking dependencies, the issues have long
since vanished.
One can re-add the dependencies in lib/rpmds.c rather easily ...
Of course, the crude hack approach to get it up and running is adding
Provides: VersionedDependencies = 3.0.3-1
Provides: PayloadFilesHavePrefix = 4.0-1
....
to the rpm5 spec file, but I prefer to stay off junk like that.
Before digging
deeper, does anyone have any ideas why apt is seeing those bogus
requirements
instead of the correct rpmlib(PayloadIsBzip2) <= 3.0.5-1 type deps?
(The
packages are ok, rpm --requires shows the correct deps.)
Yes, you don't want to be adding rpmlib(...) dependencies to
packages, very much
the wrong thing to do, the rpmlib() dependencies MUST be satisfied by
the rpmlib implementation,
not from packages. Adding to packages would just raise false
expectations.
OTOH, you can retrofit any dependencies by adding to /etc/rpm/sysinfo/
Providename,
that's likely what I would do.
Hmm, but you seem to be asking where the rpmlib(...) wrapping went.
The parser for "name spaces" is in rpmdb/rpmns.c, different classes
of dependencies
have their foo(...) wrapper parsed off. Look in lib/depends.c
unsatisfiedDepends() for the main
usage case for rpmnsParse().
But try re-adding the ancient rpmlib(...) deps in lib/rpmds.c first,
that will likely Just Work.
